beep-code-lookup
A PC that cannot show a picture still tries to tell you what is wrong: with beeps, with a blinking light, or with small LEDs on the board. Type what you hear or see, such as "dell 4" or "1 long 3 short". The meanings differ between vendors, so start with the name on the machine or the BIOS vendor on its start screen.
before you count
- Count twice. Note long and short beeps and the pauses. A phone recording helps.
- Know whose code it is. Brand PCs (Dell, HP, Lenovo) use their own patterns. Self-built PCs follow the BIOS vendor: AMI on most current boards.
- No speaker is normal. Most boards have none today. Look for four small lights near the memory slots or a two-digit display.
- Most codes end in the same three places: memory, graphics, or the board itself. Reseating the memory fixes more of them than anything else.
Beep codes changed between BIOS generations and differ by model. The entries here are the common meanings: the manual or the vendor's support page for the exact model wins when it disagrees. Related: wizard: the PC does not start, desktop PC hardware guide, notebook hardware guide, stop code lookup.
